Hello! I have went from forum to forum asking about my game. As far as I know, no one knew it existed until I asked. The game is Pokemon Green Limited Edition Release. This came in a black box not the normal silver/yellow box. The box also had the different design. Yes, the design is slightly different. I only know of 3 that exists, my friend has the black box sealed, I found one for private sale (no box, no sticker), and mine. I have literally asked multiple Pokemon experts. None of which ever saw it before. This one was luckily found just after the initial release, in a Japan game store. The plastic case is the original case for the game. This never came with the limited edition black box. The game has been used 1 time to ensure it is in working order. So, here it is 1 of 3 known, rarest pokemon game on the planet. Perhaps one of the rarest Gameboy games ever made. Please, share any information you have!
